Dunno how much of an impact this would have... the tank itself is quite a ways underground. Also, here in Ontari-ari-ari-o, there is a sticker on the pump itself which says something to the effect that the flow rate is compensated/calibrated to the equivalent of X degrees (forget what actual temperature). Indicates to me that maybe the pump passes a bit more fuel in the summer than it does in the winter to compendsate for the density difference?

>> "Don't sweat it at the pump. This is not a

> but those of you who are actually enjoying
> temperatures the rest of us remember fondly as
> "warmth," try not to fill your tank at the hottest

> "more" gas for your money."
>> How much more fuel can you get in the winter if its
> several degrees colder? It can't be that much denser.
> One thing for sure, though, winter mileage is 10 - 15

>> Another thing I have noticed is that the Premium
